PERCOLATOR.

Specification of Letters Patent.

Patente Oct. 27, 1914.

Application filedAugust 1, 1913. SerialNo. 782,447.

infusion, a reservoir to contain water orv otherliquid to be used in preparing the in fusion, a container for the substance from which the infusion is made, and a connection between the reservoir and the container, this connection including a liquid heating element located at the outside of the device for heating the liquid passing from the reservoir to the container, after which it escapes to the-vessel.

An object of the invention is to provide a simple, compact and efficient percolator which can be manufactured inexpensively in different forms, sizes and styles, by means of which infusions of varying degrees of strength canbe prepared from tea, coifee and other substances, with extreme rapidity, with the employment of a minimum of heat, and which is excellently well adapted for use b hunters, campers, prospectors and the hire, as well as in the household.

A further object of the invention is to provide a percolator in which but a small quantity of the liquid is heated at a time, in which any desired quantity of the infusion can be prepared without utilizing all the liquid or all the substance, in which. the liquid need'not be preheated, inwhich the infusion itself after being prepared is not again subjected to" the action of the heat.

and in which the substance is not so acted upon as to cause deleterious constituents thereof to enter the infusion. V The invention consists. in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters ,of reference, indicate corresponding parts in all the views and in which.=

Figure 1 1s a partlal vertlcal section of a percolator constituting an. embodiment of.

our invention; Fig. 2 is a transverse section on the line 2-2 of Fig- 1; and Fig. 3 is a similar view on the line 33 of Fig. 1.

Before proceeding to a more detailed eX- planationof our invention it should i be A understood that the same can. be fashioned from sheet metal or any other material adapted for the purpose. While we have for example illustrated a form ofthe perseparable from the main vessel, we can also embody the invention in a device in which these elements are permanently associated. These as well as others of the details of concolator in which the liquid reservoir is I struction form no part. of the. invention and canbe varied in accordance with individual preference and special conditions, without departing from the underlying spiritof the invention.

Referring more rim. Underneath the bottom is a layer 14 of heat-insulating material such as asbestos or the like. liquid reservoir 15, for ex ampl'e,\of cyllndrical form, is mounted upon particularly to the draw-1 ing's, we provide a main vessel 10 shown for the vessel 10, having the lower rim 16 arranged to fit within the top of the vessel. It is provided with a bead or flange l7 engaging at the upper edge with the vessel10, and serving to assist in holding the reservoir in position. The latter has a cover or top 18:

of suitable form. I

Arranged within the vessel 1 10 and extending vertically from the bottom to near the top thereof is a tube 19, the lower end of which projects through an opening 20 in the bottom of the vessel. The'open, upper end of the tube is held in place against the side of the vessel, by means of an arm or bracket 21. The reservoir 15 has a downwardly extending outlet 22 of tapered form of which the flow of liquid from the reservoir into the tube 19 can be regulated and controlled. Located under the bottom of the vessel 10 is an. annular pipe 26 secured to and communicating with the lower end of the tube 19. The layer 14 of insulating material has a substantially central opening 27 which registers with the lower open end of pipes 29 extend upwardly through the tubes an upwardly extending tube 28 arranged within the vessel and of tapered form. It is disposed centrally with respect to the vessel and terminates near the top thereof. The pipe 26 encompasses a number of smaller, radial pipes 29, the lower, outwardly disposed ends of which are secured to and communicate internally with the pipe 26. "The 28, having their upper ends secured in the upper extremity of this tube. V

A perforated container 30 for the tea, coffee or other substance is removably arranged upon the upper end of the tube 28, having an internally disposed open ended tubular part 31 proportioned to receive the end of the tube 28so that the container can be mounted upon the same. The container maybe of any suitable form and is preferably of roundedshape, the lower part thereof being provided with a number of perforations 32. An imperforate' cover 33 of suitable rounded form fits upon the open top of the container, which is located, as will be seen, closely adjacent to the under side of the liquid reservoir 15. The container may be fashioned from'screen or any other suitable reticulate material.

lVh'en" our percolator is in use the water or other liquid which is to be used in the infusion is placed in the reservoir 15. Tea, coffee or other substance is placed in, the container 30, which is mounted upon the upper end of the tube 28. Heat is applied to the radiator by means of an open flame or if so desired the percolator itself can be set directly upon a stove. The valve 25 is opened to allow water to flow through the outlet 22 into the tube 19 and through the radiator where it is at once heated. The water heated in the circular pipe 26, as well as in the horizontal portions of the pipes 29, will rapidly rise in temperature, and due to the small diameters of the pipes 29 the water therein will readily turn to steam, thereby accelerating the outflow of the liquid heated into the circular pipe 26 through the small pipes 29. The hot vapors in the vertical portions of the pipes 29 are prevented from condensation therein by the heat entering the pipe 28 and also by the flow of steam constantly generated by the heater in the horizontal portions of the pipes 29. The hot vapors and steam rising through the pipes "a condenser. Steam escaping from the pipes 29 is thus condensed and falls upon thesubstance in the container, in the form of liquid. In this way, the strength of the infusion is augmented. It will also be noted that the infusion itself is not again subjected directly to the action of heat, being protected 'bythe layer of insulatingmaterial 14:.

Having thus described our invention, we
